The invention relates to an improved separable press-table for brickpresses, consisting of a frame, enclosing a rectangular opening, inwhich shorter and longer mould compartments for bricks of differentsizesmay be provided, without exchanging or disconnecting the frame elementsof the press-table.

In the accompanying drawings:

Fig. 1 is a top View of the press-table showing the features of thisinvention.

Fig. 2 is a section through the press-table along the line N O in Fig. 1showing two adjacent mould openings arranged abreast of on another. j

Fig. 3 is a section through the press-table along the line P Qjin Fig.1.

Fig. 4 is a section alon the line B S in Fig. 1, demonstrating theetachable connection of the frame elements of the press-table.

ings, connected and held in position byfour' pillars 31, which alsosupport between the two press-cylinders a pair of fixed parallel frameelements 29. a The distance apart of the fixed frame-elements 29 issecured by a pair- V of detachable frame elements 30 connected to' 30the frame element-s 29 by bolts 32. The two pairs of frame elementsforming the frame f of the presswtable enclose a rectangular open 1nwhich the elements of the moulding with mammal. 3.

The inner sides of. the side cheeks 1 and 2 are provided with grooves,which support the transverse walls 3 of the mould compartments by meansof suitably shaped projections 4 at both'ends of the transverse walls 3.The transverse walls 3 are protected against wear by linings 15 alsosupported in the grooves of the side cheeks 1 and 2 by suitableprojections 5 the length of which is greater than the'depth of thegrooves. These longer projections 5 of the linings 15 support thelinings 16, protecting the side checks 1 and 2 against wear, andprovided with lateral slots by means of which they are held on theprojecti0ns of the linings 15. i

The parts ofthe grooves in the side cheeks 1 and 2 behind the linings 16and between the projections of the linings 15 arefilled up by fillingblocks 18', the length of which determines the width of the mouldcompartment whereas its length is determined by the length of thetransverse walls 3. 7

Set screws 36, arranged in the fixed frame 7 elements 29 bear againstthe outer transverse walls 3 which serve as end blocks.

In the example shown in the drawings two mould compartments for largebricks are distance apart of the fixed frameelements29.

' Also longer and shorter transverse walls 3 and linings 15 may beintroduced between the longer or shorter bricks. K. i -35 Afterintroducing the transversel'walls, linings and filling blocks adaptedfor; thedesired size and number of mould compartments betweenit he"adjustable side cheeks 51 and 2, the I latterare brought and held f; in:position 0 by suitably turning on the set screws 34 and 35. The rightposition of the mould compartments between the side cheeks l and 2is-adjusted and secured by suitably turning on the set screws 36. As theside cheeks 1 and 2 guided in the grooves of the fixed frame elementsmay be shifted in one direction and the transverse walls, linings andfilling blocks may be removed gliding in the grooves of the sidecheeks'vertically to the shifting of the side cheeks, it is easy toadjust the mould compartments truly to the position of the correspondingupper dies 37 and lower dies 38, fixed respectlvely to the upper andlower press piston.

If other sizes or numbers of mould compartments are to be provided it isonly necessary to loosen. the set-screws 34, 35 and 36, to

, withdraw the side checks 1 and 2 outwardly tillthe projections of thetransverse walls 3 and the linings 15 come out of the grooves in theside-cheeks 1 and 2, and to exchange the transverse walls, linings andfilling A tween the frame elements 29 and 30 facilitates the true andexact shaping of the frame elements and the mounting of the side cheeks1 and 2 the lateral projections 33 of which may be easily introducedinto the grooves of the fixed frame elements 29 after removing one ofthe detachable frameelements 30.

When necessary, for instance for repairing, or exchanging the pistons ofthe press-cylinders, both the side cheeks and the detachable frameelements may be removed after taking out the bolts 32.

I declare that what I claim is 1. A press includingin combination apresstable forming a frame of generally rectangular shape connected withthe press, a pair of side cheeks adapted to slide between and supportedby two opposite sides of the frame, means mounted in the other oppositesides of the frame for ad'usting said side cheeks relatively to the sies of the frame which support the side-cheeks, a plurality of transversewalls displaceably mounted between said side cheeks and means foradjusting said transverse walls relatively to said side cheeks.

2. A press including in combination a press-table forming a frame ofgenerally rectangular shape and consisting of a pair of fixed parallelframe elements connected with the press and a pair of detachable frameelements, a pair of side cheeks adapted to slide between and supportedby the fixed pair of frame elements, means mounted in the detachableframe elements for adjusting said side cheeks relatively to the fixedframe elements, a plurality of transverse Walls displaceably mountedbetween said side cheeks and means for adjusting said transverse wallsrelatively to said side cheeks.

3. A press including in combination a press-table forming a frame,consisting of a pair of fixed parallel frame elements provided withgrooves at their inner surfaces, and a pair of detachable frameelements, a pair of side cheeks mounted between said fixed frameelements provided with lateral projections fitting into and displaceablysupported by the grooves of said fixed frame elements, provided furtherwith grooves at their inner surfaces, a plurality of transverse wallsmounted between said 'side cheeks having projections at both endsfitting in and displaceably supported by the grooves in said sidecheeks, means for adjusting said side cheeks relatively to said frameand means for adjusting said transverse walls relatively to said sidecheeks.

4. A press including in combination a press-table forming a frameconsisting of a pair of fixed parallel frame elements provided withgrooves at their inner surfaces and a pair of detachable frame elements,a pair of side cheeks mounted betweensaid fixed frame elements providedwith. lateral projections fitting into and displaceably supported by thegrooves in said fixed frame elements, provided further with grooves attheir inner surfaces, a plurality of transverse walls mounted betweensaid side cheeks having projections at both ends fitting in anddisplaceably supported by the grooves in said side cheeks, fillingblocks inserted in the grooves of said side cheeks between saidtransverse walls, adapted to space apart said transverse walls, setscrews arranged in said detachable frame elements bearing against sideside cheeks and set screws arranged in said fixed frame elements bearingagainst the outer transverse walls.

5. A press including in combination a press-table forming a frameconsisting of a pair of fixed parallel frame elements provided withgrooves at their inner surfaces and a pair of detachable frame elements,a pair of side cheeks mounted between said fixed frame elements providedwith'lateral projections fitting into and displaceably supported by thegrooves in said fixed frame elements, provided further with grooves attheir inner surfaces, a plurality of transverse walls mounted betweensaid side cheeks having projections at both ends fitting in anddisplaceably supported by the grooves in said side cheeks, transverselinings for taking wear arranged against said transverse walls providedwith lateral projections fitting into the grooves of said side cheeks,linings for taking wear arranged against the side cheeks between thetransverse linings and having lateral slots fitting on the lateralprojections of the transverselinings, filling blocks inserted in thegrooves of said side cheeks between the transverse linings adapted tospace apart said transverse linings and transverse walls, set screwsarranged in said detachable frame elements bearing against said sidecheeks and set screws arranged in said fixed frame elements bearingagalnst the outer transverse walls.

In testimony whereof I have signed my name to this specification atBerlin, Germany. Y
